                Fact  Sheet
          The Environmental Protection Agency (EPA) is proposing to amend regulations
       governing incinerators burning hazardous waste. This proposal is designed to reduce
       and control toxic pollutants like metals and organic emissions, and to ensure uniform
       regulation of all devices burning hazardous waste for any reason. The rule also
       broadens the definition of industrial furnace to include nonflame combustion devices
       and clanies or revises the regulatory status of carbon regeneration units, sludge  '
       dryers, plasma arc, and infrared incinerators.


 BACKGROUND
 Hazardous waste can be burned in incinerators, boilers, and industrial
 furnaces for specific, but different purposes. Incinerators use
 controlled flame combustion to treat or destroy hazardous waste, and
 have been regulated under RCRA, Subpart O since January 23 1981
 While Subpart O contains specific permitting and operating
 requirements for incinerators, EPA has decided these standards need
 to be upgraded for various reasons.

 EPA is proposing to strengthen  existing regulations for hazardous
 waste incinerators in response to the growing problem of, and public
 concern about, toxic emissions  from these devices. These stricter
 standards will ensure that incinerators do not pose unacceptable
 health risks As land  disposal decreases, the proposed amendments
 will ensure that wastes diverted to incinerators will be burned safely.

 ACTION
The Agency is requesting comment on the proposed amendment to the
incinerator regulations. This action, along with the separate proposed
rules for boilers and industrial furnaces, will establish regulatory
controls to ensure that potentially harmful contaminants are not
released to the environment when hazardous waste is burned for anv
reason.                                                      J

The amendments also:

   o  Revise the definition of industrial furnace to refer to thermal
     treatment rather than controlled flame combustion. Thus r
     name devices like electric arc smelting furnaces processing
     hazardous waste are regulated as industrial furnaces
   o  Revise and clarify several permitting procedures:

           based controls on metals and hydrogen chloride emissions

      (2)   Permit writers have the discretion to allow nontoxic surro-
           gate compounds to be used as POHCs for purposes of
           demonstrating compliance with the destruction anrl rpm,ai
           standard.                       ucsuucuon ana removal


      (3)   2S3lSi h ^T^ emergency relief valves must be in-

                               waste, and respond to slcnificant

    , wastes diverted to incinerators will be burned safely.

-------
In conjunction with the Agency's proposal to regulate hazardous
waste burned in boilers and furnaces, these regulations will make all
devices burning hazardous waste for any reason subject to identical
emission controls.  Currently, this rule affects approximately 250
facilities: about 50 new permits and around 200 permit renewals.
